Speaking about the Worboys case, he stormed: “I don’t care what the legal advice is, doing a judicial review would be a way of showing the Government feels it’s the wrong decision, even if there’s a 10 per cent chance, you get a good QC you never know. It’s just too flipping wet.”

Mr Boles moved Tories to tears when he turned up in the Commons in a wheelchair during his cancer treatment a year ago to vote through the Article 50 legislation triggering Brexit.

He returned to constituency work last September and has published a set of policy papers since – including plans to rebrand National Insurance to fund the NHS. Writing in the Sun last November, he urged the PM to give councils the power to buy green field land as part of a Budget blitzkrieg to solve the housing crisis.

Theresa May has suffered attacks over the winter crisis in the NHS and the demise of Carillion since the New Year.

And she enraged some backbench MPs with a Cabinet reshuffle where few senior positions were changed – and men were overlooked for jobs in the Whips office.

Mr Boles – Minister of State for Skills between 2014 and 2016 – was one of those overlooked.

Tonight, senior Tories spoke out in support of his outburst.
